Not safely the downpipe could cause an issue. I would wait to install til you can get a tune. The tune itself if done by a good tuner is the best "mod" you can ever do.

 

Agreed ?

 

It's should be fine without tune since you still have your cat in place.

 

I would take this with a grain of salt.

Adding the intercooler can throw things off because it will be larger. And more efficient.

Same with the exhaust manifold.

I wouldnt run anything but a catback exhaust without a tune. Only if i had an afr and boost guage so i could regulate what is going on in my engine

 

How would a gauge regulate that?

Lol, when was the lat time you looked at the AFT gauge when you were WOT...(be honest with yourself)...

Answer is no - not safely. If you stay off WOT, you will be fine. If you WOT, you are playing with fire.

 

Dont WOT at all with out a doubt. I was trying to say that i wouldnt even attempt to drive the car if my afr values are out of a safe range

 

If you will just drive normally you will be fine until you get a tune, just don't boost too much and definitely no WOT.

 

Thanks for all the advice. I appreciate it. Can I run the K&N Intake/Upper Intercooler pipe with a catback? Leave everything else off for now?

 

You'll need a tune for it, even when I had only a ETS catback and a K&N panel filter, I used a COBB stage 1 tune. Evo's pretty much need a tune for just about any power mod. lol

 

I think the kn filter will put more unmeasured air into the engine and make you run lean.

 

I find this odd it’s what the maf is for it also has a map too

 

If the K&N intake reuses the stock MAF housing, you will be mostly alright, might be idling a bit rough, but mostly alright. If it uses it's own MAF body of a larger diameter, you need a tune.

MAF is there, but MAF is scaled in the tune to adjust for the specific airflow pattern that is influenced by your intake, hence why you need a tune if you change the MAF housing.

 

Honestly, you shouldn't hurt anything with the stock tune since it's conservative. Your car just won't run as quickly as it should.

But if you're ready for a tune, consider this:

I would be very cautious with statements like this. My stock tune knocked 9 counts with exhaust and cone filter on local gas here when finally logged. I would not risk it as some will make it fine, others will blow depending on temperature, gas quality, driving style, etc.

 

with those mods at would at least get an OOTB tune, usually your fine to drive to a shop but i really wouldnt do much more than that

 

I'm just trying to save myself as much money on labor as possible. Technically I can install everything on my own. The concern is driving it to the tuner with these mods. I don't want to risk anything at all. Maybe what I'll do is install everything and tow it to the tuner?

Thanks again everyone

 

All of these mods are safe to drive with, so go ahead and install them. Just drive normally, don't floor it. The danger is usually in high boost areas of the powerband.

 

Got it.


Thanks
